Getting in is not the same as enrolling. Watch for binding early decision terms, deadlines that arrive before May 1 and the double deposit trap that can cost you an offer.

The acceptance letters have arrived, and it is tempting to treat what comes next as a formality. It is not. The weeks between the offer and the enrollment deadline are where applicants make some of the most expensive mistakes in the entire process: misreading binding terms, missing a deadline buried in the packet, or putting money down at two schools at once. Each mistake below describes what typically goes wrong and what to do instead.

Treating the Acceptance Letter as the Whole Deal

An offer of admission is conditional, and the conditions live in the fine print. Colleges expect your grades and conduct to hold through graduation, and they ask about disciplinary history on application forms for a reason. Many also require a final high school transcript, and a student who has deposited often cannot finish orientation or register for classes until that transcript arrives. An offer can come undone after the celebratory phone call, so read the conditions section of the letter before you frame it.

Also understand what the letter does not ask of you. NACAC’s ethics guidance says colleges should not ask candidates, their counselors or their schools to divulge or rank order their college preferences, and that students have the right to compare financial aid packages, merit scholarships and other factors that cannot be known until every offer is in hand. If an interviewer or admissions officer presses you to name your first choice, you can decline politely. You owe the school an honest application, not a ranking. Our glossary of college application terms defines the vocabulary used in offer letters and award notices if any of the wording is unfamiliar.

Assuming Every Deadline Is May 1

May 1, the National Candidates Reply Date, is the anchor of the admissions calendar. NACAC’s code of ethics requires colleges to leave first-year fall applicants free to weigh every admission offer, along with institutional aid and scholarships, up to that date. Binding early decision plans and athletic scholarship awards fall outside that protection.

The mistake is assuming May 1 is the only date in the packet. Scholarship acceptance deadlines can fall weeks earlier, and housing, orientation and registration often carry their own dates. A college can remind you that you have until May 1 to enroll while still asking for a scholarship decision in March or April, and that request deserves scrutiny before you answer it.

One more wrinkle: after NACAC revised its ethics code, colleges are permitted to offer incentives to prospective students and to keep recruiting applicants who have already deposited somewhere else. Financial aid offers can keep arriving into the summer. That does not move your deadline. It just means the phone may keep ringing after you have decided, and a later offer from another school does not undo a commitment you made to a binding plan. If one of your options admitted you on a rolling basis, remember that rolling admissions schools set their own schedules, so confirm when their commitment and housing deadlines fall rather than assuming they match everyone else’s.

Misreading Early Decision and Early Action

The terms sound interchangeable. They are not.

Plan	Binding?	What you are agreeing to
Early decision	Yes	To attend if accepted. You may apply early decision to only one college.
Early action	Usually no	To an earlier decision, with no commitment to enroll. Some restrictive early plans are binding, so read the terms.
Regular decision	No	To nothing beyond a timely reply by the school’s deadline.

Early decision is the one people misread. Applying early decision means agreeing to attend if accepted, and you cannot apply early decision at more than one college. Many colleges ask counselors to sign their students’ early decision applications, and NACAC guidelines bar a counselor from signing more than one per student per application season. Once you are accepted under a binding plan, you are expected to withdraw your other applications immediately. The only acceptable reason not to is that you are still waiting to hear about financial aid.

Double Depositing

Double depositing means putting down a deposit, and therefore accepting admission, at more than one college. Deposits typically run between $50 and $500, are usually nonrefundable, and apply toward tuition if you enroll. Since a student cannot attend two colleges, the practice is considered unethical, and people do it for predictable reasons: to buy more time, to keep negotiating financial aid past May 1, or to hold a seat while waiting on a waitlist.

The consequences are real. The Common Application requires students to affirm they will deposit at only one institution and warns that sending multiple deposits may result in withdrawal of admission offers from all of them. Colleges do check, and they will rescind offers when they find it. The logistics catch people too, because a high school sends its one final transcript to a single college.

The damage spreads beyond you. Colleges build budgets and class schedules around the deposits they receive, and a large summer melt has forced institutions to cut office hours, student activities and services. A double depositor also holds a seat that could go to a waitlisted student.

Adviser’s tip: If you honestly need more time, call the admissions office and ask instead of depositing twice. Some colleges will discuss an extension or a later decision on a scholarship; they cannot help with a request they never hear.

Handling Waitlists Clumsily

The workable sequence is straightforward. Accept your best firm offer and deposit there, then stay on the other school’s waitlist if you still want the spot. NACAC treats this as the one acceptable case for holding a place at a second college. What you cannot do is keep both deposits after the waitlist school admits you. If you come off the waitlist, notify the first college in writing immediately so it can release your seat to someone else.

Accepting Verbal Promises

Because colleges can now offer incentives and keep recruiting after May 1, a recruiter may promise a matching aid package, a housing preference or a scholarship over the phone. The whole point of the May 1 reply date is to give students room to decide with all offers in hand and without pressure, and a promise you cannot document is a promise you cannot enforce. Ask direct questions and get the answers in writing before you commit. A scholarship email that demands a decision well before May 1 is worth a follow-up question too: ask exactly how accepting or declining the award by that date affects your right to decide on enrollment by the national reply date.

Honesty runs both directions. Do not tell more than one college it is your first choice, and do not misstate your intended major to improve your odds. Those are the same ethics rules colleges are held to, applied to you.

Ghosting the Colleges You Are Declining

Failing to notify the other colleges that accepted you, once you accept an offer somewhere, is listed among the basic ethics violations in the application process. It also has a practical cost to other students, because a prompt decline frees a seat for someone on the waitlist. Send a short written decline to each school that admitted you. It takes minutes and closes out your file cleanly.

A Short Checklist Before You Say Yes

Work through these items before the deposit leaves your account:

• Reread the offer letter for conditions, including final grades, transcripts and conduct.
• Confirm which of your plans are binding and whether any early commitment still applies to you.
• List every deadline in the packet: reply date, deposit, scholarship acceptance, housing and orientation.
• Verify the deposit amount, whether it is refundable, and what it applies toward.
• Get every financial aid and scholarship promise in writing, with amounts and renewal terms.
• Accept one offer and decline the others in writing.
• If you are waitlisted elsewhere, keep exactly one enrollment deposit and follow up on the waitlist separately.

Do that, and the decision you announce on May 1 is the one that actually holds.

Readers ask

Can I deposit at one college while staying on another school’s waitlist?

Yes. The National Association for College Admission Counseling treats the waitlist case as the one acceptable reason to hold a place at a second college, and it recommends accepting your best firm offer first. If you are later admitted off the waitlist, notify the college you are leaving in writing right away.

What happens if I pay deposits at two colleges?

It is considered unethical because you cannot attend both, and colleges do check. The Common Application requires you to affirm you will deposit at only one institution and warns that multiple deposits may result in withdrawal of admission offers from all of them.

Does a college have to let me decide by May 1?

NACAC’s ethics code holds admission and institutional financial aid offers open for first-year fall applicants until May 1. Binding early decision plans and athletic scholarships sit outside that rule, and some scholarship decisions come due earlier.

Do I have to tell a college it is my first choice?

No. NACAC’s guidance says colleges should not ask applicants, counselors or schools to divulge or rank order their college preferences. Comparing financial aid and scholarship offers is your right, and those offers are not fully knowable until every one is in hand.
